By the u-se of my invention either kind of record can beplayed or used on the one machine Without any foreign or disturbingnoises being perceptible.

My invention comprises' two tracker devices one to be used on a recordhaving the laterally arranged indentations and one tof be used on arecord having the shallow and deep indentations, both or said devicesbeing properly connected to the diaphragm of the machine to vibrate thesame when tracking over a record. Oi? course the one device has thetracker needle in proper position to vibrate the diaphragm when trackingover a record having thev laterally or zig-zag arranged indentatioifs.and the other device a point in proper po "tionl to vibrate thediaphragm vvhentracI over a record having the shallow and deep intations.

ragga make and use the `same I have illustrated it :on the 'accompanyingsheet of drawing torming a part of this specification. m which:

lar parts throughout-the several views.

Infthe drawings I have not attempted to showffan entire machine,V butonly;` the v'sound box 65 with thetvvo4 tracker dewi'cesconnectedthereto. The sound bon 6 isconlrectedf to the horn in'lfthe usual wayllbyf means lof the slip or threaded ljoint 7j. Th'efdiaphragm 8 .issecured in the". boX `in any' of the; well known manners and has securedtojits'center, one end of the vibrator arm 9 in the usual way,andsaidarmv 9 extends radially able bracket 11 secured rigidly to t-heboX 6. The pivot 10 is arranged in such position that the vibrator arm 9is free to move with the center of the diaphragm when the sameinconnectionwith a record having the ziglzag indentations which causethe needleto move laterally as it tracks over the same.

The vibrator arm 9 is provided with a second extension or arm 15 whichextends at right angles to the axis of pivot 10 and at right angles tothe axis of the lateral inotion needle 14.' The free end of arm 15 ispivotally connected tov one end of the tracker rod 16 provided with thepoint 17 which I shall designate as the longitudinal motionl pointbecause it is employed in connection with arecord having the shallow anddeep indentations which give the point a longitndinal movement when ittracks over the same. The remaining end of the tracker rod 16 is guidedduring its slight longituoutward beyond the limits" of the 'box y 6where it is pivotally mounted at 10 to a suit- 4 sounds, whichis'securely mountedy in the'end of a bracket 19'rigidly secured to thebox 6.

-, The point 17 is madeof sapphire or other suitable stone lor metal. Asclearly shown .in Fig. 4, the'longitudinal motion tracker f rod 1G maybe provided with a slightly ta- 4pering lower extremity onto which maybe secured a tip 20 having a correspondingly tapering hole and providedwith a rounded or dull point 21. The said point 21 is employed inconnection with special records Whose indentations are made to operateWith a rounded or. dull point.

From the description given it will be understood that when a recordhaving zigzag indentations is 4used in the machine a lateral motionneedle 14 is secured in the extension 12, and when a record havingshallow and deep indentations is used in the machine the lateral motionneedle is removed so that the longitudinal motion point 17 of thetracker rod 16,is free to contact with the surface ofthe record.

Obviously when the lateral motlon needle i 14 is employed the vibrationsWill be trans'- mitted from` the record through the needle 14, extension12, vibrator arm 9 and thence to diaphragm 8; and when the longitudinalmotion point 17 is employed the vibrations will be transmitted from therecord through tracker rod 16, extension orarm 15,l vibrator arm 9 andthence to the diaphragm 8.

Thus it is clear that the vibrations will be Lacasse transmitted to thediaphragm` 8 ifeither of the tracker devices is employed.

It will be understood that .the material size and arrangement andconstruction of uthe parts may be modified without lin the leastdeparting from the scope of my invention.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent of the United States is 1. In a device ofthe class described, a diaphragm, a vibrator arm having one endconnected to said diaphragm, means whereby, a lateral motion trackerneedle is opera# tively connected to said Vibrator arm, means whereby atracker rod carrying a longitudinal motion tracker point is pivotallyconnected at one end to an extension on the vibrator arm and meanscomprisinga bearing provided with sound insulating material for guidingthe free end of said tracker rod.

2. In a device of the class described, a tracker rod provided at one endwith a tracker point and arranged to move longitudinally when vibrated,a bearing for one end of said tracker4 rod lined with'sound insulatingmaterial, and a pivoted angular bar pivotaliy connected to the otheryend of said tracker rod. p a
